Toall whom it may concern: 1

Be it known that I, I-IonAoE D. WEBB, a

citizen of the United States, residing at V sole after the insole isattached to a last.

The insole channeling operation frequently causes anappreciableelongation of the insole. The inferior material of which itis often made and the fact that it is channeled while in tempercontribute to the produc-tion of this effect, as a consequence of whichthe insole fails to fit the last when applied to it. It has become thepractice, therefore, to apply the insole to the last in such manner astoregister with it at the toe tip, and to trim off the surplus at theend. of the heel.

A difficulty also arises due to; the faulty shaping or to the changingin shape of the insole after its initial shaping, it being found that itis frequently too fat or wide in the shank and heel breast portions.This makes it desirable to trim all around the heel, instead of merelyat the end thereof.

In machines used for this purpose prior to the present invention, thelast with the insole tacked on it was supported on a jack and presentedto a revolving cutter, the last resting against a gage as it was turnedaround on its thimble axis to present the heel-periphery of the insoleto the cutter. \Vhen trimming insoles which were fat in the shank, itwas found that the cutter left an abrupt concavity where it stoppedtrimming near the end of the shank edge. The corner between thisconcavity and the shank edge had to be trimmed by hand to avoid causinga hump in the upper of the completed shoe near the heel breast.

An object of the present invention is the correction of the diflicultydescribed.

In accordance with one important feature ceases to treat the work. showncomprises a work support for holding of the invention, mechanism isprovided for guiding the work in desired relation to the operating meansfrom a templet, according to a corresponding relation between thetemplet and the operating means, and for changing the relation betweenthe templet and operating means at a predetermined part of the work toguide the operating means tothe edge of the work. In the machine shown,a last with an insole attached is moved relatively to the operatingmeans with the edge of the last in alinement with the operating meansuntil a predetermined portlon of the work has been reached, and then ismoved to carry the edge of the last out of alinement with the operatingmeans to lead the line of operation out of the work.

Another feature of the invention is the combination of operating meansand a work support arranged to carry the point of contact of theoperating means around the work and to lead it out of the work when apredetermined point thereof has been reached in such manner as to insurea smooth condition at the place where the operating means The machinethe edge of the last in alinement with the trimming means, and formoving it gradually out of alinement with the trimming means whenapredetermined portion of the work has been reached. This organizationinsures trimming the insole to register with the contour at the back andsides of the heel, sloping the lineof cut out to the edge of an 'inso-le.fat at the shank.

Another feature of the invention is the actuation of the mechanism forcontrolling the line of cut by the movement of the work itself,irespective of guiding effort on the part of the operator. The properplacing of the line of cut 'in the work is thereby made positive andindependent of skill on the part of the operator.

A further feature of the invention resides in rotating the work relativeto an operating means, and swinging it about an axis distinct from theaxis of the first-mentioned rotation, the latter axis being so arrangedas to separate the operating means and the work. This combined rotationabout two axes causes a gradual shift of the work from the operatingmeans, the line of treatment is thus led gradually out of the work, anda smooth even result is produced.

binations of parts will be understood from the following decription of-apreferred embodiment of the invention, selected for purposes ofillustration and shown in the accompanying drawings in which;

Figure 1 is an end view in elevation of an insole heel seat trimmingmachine, in.- cluding novel work positioning means in which the presentinvention is embodied;

Fig. 2 is a perspective view of thenovel work positioning means asviewed diagonally from the left with reference to Fig. 1;

Fig. 8 is a view in section through the cutter and adjacent portions ofthe illustrated machine showing the manner in which the work ispresented for treatment.

Fig. 4 is a detail, partly in section, of the controlling apparatus;

Fig. 5 illustrates the novel action of my work support, in combinationwith the trimming means;

Fig. 6 illustrates diagrammatically the advantages secured by myinvention;

Fig. 7 is a detail illustrating the action of the work supportingmechanism; and

Fig. 8 illustrates themovement ofthe point of contact between the lastand the gage.

The machine illustrated comprises a frame 2 having bearings for a rotaryshaft 4 which carries a toothed cutter 6 and the usual shield 8.Positioned at the end of the cutter is a guide member 10 constructed forengagement with the lateral surface of a last (Fig. 3) adjacent to theedge of the heel seatto guide the last in its turning movement duringthe operation of trimlning around the edge of the heel portion of theinsole 11. This guide member has a lip 12 projecting between the bottomof the last and the insole for the purpose of positioning the lastaxially of the cutter and supporting the insole out of contactwith,

the last adjacent to the point of operation of the cutter, as well aspreventing any possible engagement of the cutter with the last, all asmore fully explained in the patent to Keyes, No. 1,076,431, Oct. 21,1913, which shows a similar construction.

The guide member 10 is mounted adjustably in a support 14 which ispivoted to the frame 2 at 16 to permit the member to be swung away fromthe cutter when it is desired to remove the cutter from its shaft.Mounted upon the shaft 4 also to rotate therewith is a presser member 18which is movable lengthwise of the shaft and during the trimmingoperation is held by means of a light spring 20 against the insoleadjacent to the point of cut to assist in preventing the insole frombending away from the cutter. A collar 22. secured to the shaft by ascrew 24 that pro jects through a slot 26 in a sleeve 28 extending fromthe member 18 serves as an abutment for the spring 20 andby engagementwith the inturned end of the sleeve determines the idle position of thepresser member 18 so as to permit the insole to force the memberbackslightly in opposition to the spring 20 when the insole is presented tothe cutter. The member 18 is shown as formed as a spiderwith its armsextending between the teeth of the cutter 6, so that the edge of theinsole 11 may be pressed firmly between the shield 8 and the lip 12 onone side and the spider 18 on the other, without interfering with theaction of the cutter 6.

Secured upon one side of the lower portion of the frame 2 is a bracket80 provided with a horizontal arm upon which the work supportof themachine is mounted. This arm is provided with a bearing for thereception of a stem 34 which projects from a block not shown bearingagainst the rightend of the bearing of the arm 32 as seen in Fig. 1.Projecting from the block atright angles to the stem 34 is a rod 40which provides a bearing for the upwardly extending arm 42 of the worksupport. Mounted upon the upper end of the arm 42 is a head 44 having astem 46 which engages in a bore in an offset portion of the arm so thatthe head may turn in a plane transverse to the arm. The head 44 hasdepending therefrom a pin 48, which enters a recess formed in the-upperend of the arm 42, and threaded through the arm at opposite sides arescrews 52 the inner ends of which extend into the recess and serve, byengagement with the pin 48, to limit adjustably the turning movement ofthe head 44 in both directions about the axis of the stem 46. Thepurpose of such turning movement of the head 44 will be hereinafterexplained.

Secured in a bore in the head 44 is a sleeve 54 through which extends aspindle 56 the forward end portion of which is arranged toenter the lastpin socket of a last as shown in Fig. 2. The spindle 56 is free both tomove endwise and to turn within the sleeve. The sleeve 54 is extended atone side of the head to provide a bearing for a cam 58 which is mountedthereon for rotation aboutthe axis of the spindle 56, the sleeve havinga flange at its outer end-to retain the cam in position thereon. Securedto the spindle 56 at a distance from its forward end is a plate 60 whichis formed with grooves 62 to provide a slideway for a pair of lastpositioning members 64, these members being movable upon the slidewaytoward and from the spindle 56. The members 64 comprise a pair of jawsarranged for engagement with the sides of the neck portion of a last toassist in maintaining the last firmly in position upon its support.Pivoted on one sideof the plate 60 are bellcrank levers 66 in one arm ofeach of which is formed a-slotfor the reception of a pin 68 whichprojects from the corresponding jaw 64, as shown in Fig. 2.= A spring 70 is connected to the levers 66 in such manner as to cause the jaws64toassume their position of maximum separation. The other arms of thelevers 66 project inwardly in position to be-engaged by the cone of thelast when the last is mounted upon the spindle. It will thus be seenthat when a last is mounted upon the spindle and is moved to cause thespindle to approach the bottom of the last. p111 socket, the levers 66will be engaged by the last and swung about their pivots, thus causingthe jaws 64 to slide inwardly and make firm contact with the sides ofthe cone of the lastso as to prevent the last from tipping and assist inmaintaining it in fixed relation to the spindle during the trimmingoperation. I

From a consideration of the construction as thus far described, it willbe seen that including the plate .60 and the jaws 64, will serve toeffect displacement of thezlast trans.- versely of the planeof its: heelseat portion. Extending frointhe plate '60 are pins 74 which arearranged for sliding engagement in recesses in the cam 58 as the plateis moved toward or from the cam by endwise movement of the spindle 56,this arrangement serving tomaintain the. cam 58 and the last support inthe same angular relation with reference torotation about the axis ofthe spindle 56 so that the bracket and the support must rotate inunison.

The means for clamping the insole upon the last comprises mechanismmounted upon an arm 59 extending fromthe cam 58 and including amember 76which is arranged for sliding movement in substantially parallelrelation to the spindle 56. Secured upon the slide 76 by means of athumb screw 78 is an arm 80 which is formed to extend down the side ofthe last forwardly of the heel portion and is bent to-extendinwardlyover the last bottom to substantially the longitudinalmedian'line of the last. This arm carries a clamp member 82 which extendstherefrom toward the rear of the heel seat and has a plurality ofpointed pins 84 for effecting secure engagement with the insole.

- The member 82 is formed of slightly resilient material and is inclinedsomewhat with reference to the plane of the last bottom so as to permitthe clamping device to be manipulated readily notwithstanding slightvariations in the thickness of diiferent insoles or the height ofdifferent lasts.

means of a screw and slot connection 85 the clamp member is adjustablewith reference to the arm 80 to vary the position of its in- "to lastsof different styles and sizes.

sole engaging portion with reference to the rear end of the heel seat,particularly for the purpose of accommodating the (182E106 he arm 80 hasa slot 88 in which is received a projection 90 of the slide 76 tomaintain the arm in the same angular relation to the slide and permitthe arm to be adjusted lengthwise of the slide to adapt the device forconsiderable variations in the height of different styles or sizes oflasts. Pivoted at its middle portion upon the cam 58 is a lever 94, theupper end of which is connected by means of a link 96 with the slide 7 6and the lower end of which is connected by a similar link, not shown,with the plate 60 of the last support. It will be readily seen that withthis arrangement endwise movement of the spindle 56 in either directionwill cause the slide 76 and the clamp member 82 to move in the oppositedirection.

I The operating means for effecting the clamping of the insole comprisesa lever 1.04 pivoted at 102 to the head 44, and connected by links 106with a bar 108 which is mounted loosely upon the spindle 56 betweencollars 110 on the spindle. These collars are shown in Figs. 2 and 4respectively.

lVith this device the operator can readily effect with-one hand suchrelative movement of the last support and the clamp member as to clampthe heel portion of the insole securely in position upon the last andposition the last firmly upon its support for the trimming operation. Agrip member 114 on the head 44 assists the operator in operating thelever and in maintaining it in position to clamp the work while the workpositioning means, including the last support and the clamping device,are rotated through the turning movement of the last which is effectedbythe other hand of the operator.

In order to maintain the work positioning means when idle in a positionconvenient for the reception of a last, the cam 58 is provided with aweight 116' which tends to occupy the position shown in Figs. 1 and 2,thus presenting the last support in such relation to the operator thathe may conveniently mount a last upon the spindle 56 between the members64 while holding the last by the forepart in the usual manner.

It will be seen that by reason of the arrangement of the rods orspindles 34 and 40 the work support is afforded a substantiallyuniversal swinging movement to facilitate the presentation of the workto the machine. The member 42 carries an arm 120 extending adjacent thecam 58, and carrying a roller 122 arranged to contact with the cam. Thecam is low at its middle part where it normally does not engage theroller and high at its ends, as shown in Fig. 4.

In addition to the substantially universal swinging movement of the worksupport,

by reagon of the manner in which the arm 42 is mounted upon thesupporting bracket 30, the head 44, as hereinbefore explained, ispermitted to turn relatively to the arm 42 within the limits set by thescrews 52. This arrangement affords provision for such angularvariationbetween the axis of turning movement of the last and the axis of thecutter as is desirable in order to permit the insole to be trimmed tothe edge of the last bottom on lasts of different shapes.

It will be evident from the preceding dc scription that the operator maymanipulate the work support to carry the work toward or from position tobe operated upon by the machine and may also manipulate the lever 10stto effect the clamping or releasing of the insole by the use of onehand, thus permitting him the free use of his other hand to mount thelast upon the support or to remove it therefrom and to turn the last tocause the cutter to trim around the heel seat. lVith the parts in theiridle positions it is only necessary, in order to position the work, tomount a last upon the end of the spindle 56 and to swing the lever 10%toward the grip member 11st, thus moving the last toward the clampmember 82 and simultaneously moving this member toward the last bottomto effect the. clamping of the insole. As pressure is applied upon theinsole by the member 82, the last will be forced farther inward upon thespindle and the jaws 6%, through the operation of the levers 66, will becaused to press upon' the cone of the last at oppositesides to hold itfirmly in position. The operator then swings the work support to carrythe insoletoward the cutter. hen the parts-have been positioned inoperative relation to the cutter, as shown in Fig. 3, the last is turnedto cause the cutter to operate around the heel seat upon all portions ofthe edge of the insole which it is required to trim, the last supportand the clamp member and their connections, together with the cam 58,being arrangedto turn with the last, and relatively to the lever 104:,in the manner previously explained. cutter with its long axis passingthrough the shaft 4, and with its edge in contact with'the gagelO at 118(Fig. 8), and is then swung to one side and then to the other in orderto trim around both sides of the heel, as indicated in Fig. 5. Machinesof this type as they existed prior to my invention, trimmed a fat insoleas shown on the left in Fig. 6, the cutter leaving a pronounced corneror hump at 12 1 where the trimming operation stopped. Then using themachine of the present invention, however, the high points ofthe cam 58contact with the roller 122 as the last is swung toward its extremeposition The last is first presented to the and the. reaction between.the:roller and the camttufnsnthe head44 about the axis as so as to tipthe lastfgraduallya about the point of contact between the last: and:the outside corner of theguiderlO; This. point of contaet moves uptheside of the last: as it turns, as shown at 112. in: Fig; 8, thusdrawing. the last edge andinsole outof alinementwith the cutter edge:and sloping the cutigently out to the edge-of the fat portion of theinsole. A small movementntakes place about the axis-40 duringth'e-entire.operation, in order to permit the last :to remain in contactwith the gage 10.v Fig. 7shows in dotted lines the position of the lastatrthe beginning of the swing, and in full lines the position ofthe lastat the end. of the swing. The spindle holes showthe pivotal movement ofthe last and Fig. 8 illustrates how-the pivotal point of contactbetweentthe last and the gage 10moves u-pthe side of thelast as it turnsabout :this point, so asto draw the insole away from: the cutters.

It will be seen by reference toFig. 3 that thepressermember18*constructed and positioned as shownand described presents noobstruction. to the clamping. device during the-manipulation1 ofpthework: and by pressure upon: the insoleadjacent to the pointof cutassistsin preventing the insole.
